Description

Technical Field

[0001] The utility model relates to the technical field of earthwork engineering, and more specifically, it relates to an earthwork anti-dust device. Background Art

[0002] Earthwork engineering is an important project in the field of land engineering, mainly involving the excavation, transportation and filling of soil, as well as engineering technologies related to soil. When the construction team conducts earthwork engineering, a large amount of dust will be generated, increasing the concentration of particulate matter in the air, causing environmental air pollution.
